The Elka EH105: A Deep Dive into the Italian Organ That Defined a Generation of Home Entertainment

In the pantheon of vintage electronic organs, certain names evoke instant reverence: Hammond, Lowrey, Wurlitzer. However, nestled quietly among these giants is a fascinating artifact of mid-century Italian design – the Elka EH105. While not as ubiquitous as the B3 or as flashy as a Lowrey Genie, the EH105 represents a unique moment in musical history. It is a bridge between the theatrical theatre organ and the burgeoning world of portable transistors.

For collectors, vintage gear enthusiasts, and players looking for that elusive "Europsychedelic" tone, the Elka EH105 is more than just furniture; it is a time capsule of analog circuitry and Italian flair.

🔹 Feature you might be missing (common question):

“Does the EH 105 have a continuous memory feature when off?”
No — by default, turning off the calculator clears all program steps and registers. A hardware mod (adding a supercapacitor or battery-backed RAM) is required to keep memory on power-off.

Where to find one:

• Reverb.com: The most reliable source, though prices are highest.
• Leboncoin (France) / eBay Kleinanzeigen (Germany): Elka was common in Europe. You will find cheaper units in France, Italy, or Germany.
• Thrift stores: Still possible, but rare. Look for any beige organ with "Elka" written in cursive.

Safety & maintenance

• Use on flat, stable surfaces; keep clear of flammable materials.
• Check for functional tip-over and overheat protection.
• Clean intake/exhaust and fan periodically; unplug before servicing.
• Replace if cords or housing damaged.

Based on the manufacturer designations of the era, the proper paper size for the Elka EH105 electronic calculator (produced in the early 1970s) is 2¼ inch (57 mm) width adding machine tape.

Here are the specific details for purchasing the correct paper:

Specifications:

• Width: 2¼ inches (57 mm)
• Core Size: Standard ½ inch or ¾ inch core (usually fits, though older machines sometimes had larger spindles, 57mm is the tape width standard).
• Type: Single-ply or Two-ply (bond) paper.

Why this size? The Elka EH105 is a portable printing calculator from the early 1970s. During this period, there was a split in paper standards:

• Portable models (like the EH105) typically used 2¼ inch (57 mm) rolls to keep the device compact.
• Desktop models (like the Elka 22, 23, or 24) typically used the wider 3 inch (76 mm) or 3½ inch rolls.

Buying Tip: When searching for paper, you can look for "Adding Machine Rolls," "Calculator Paper," or "Cash Register Paper." Ensure the width is explicitly 57mm or 2¼ inch. Standard thermal paper (used in modern POS systems) will not work unless the machine has been modified; the EH105 originally required bond (non-thermal) paper. However, the width standard remains the same.
